Which risk during rapid throttling of a reciprocating compressor increases when inlet cooling fails?

A)Valve flutter and material fatigue
B)Exceeding the stoichiometric fuel ratio
C)Localized phase-locked loop oscillation
D)Increased parasitic eddy current losses

💡 Explanation

Valve flutter risk increases because surge pressure waves initiate repeated valve closures leading to mechanical stress via resonant excitation. Therefore, valve flutter risk rises rather than autoignition or electrical effects; hotter intake amplifies surge.
